Jupiter's moon Europa has an enormous salty ocean, probably heated from below by hydrothermal vents. Now it seem that Europa has an internal source of carbon, too -- making an even more exciting argument that life could exist there.
One interesting detail I couldn't fit into the story:
NASA's Galileo probe visited Europa up close, but wasn't able to see the carbon dioxide deposits on the surface. Every time Galileo got close to Europa, Jupiter's intense radiation blinded its sensors.
Scientists had to step back 500 million miles to get a clear view! #space#exploration
Interesting article in Scientific American discussing barriers to permanent human colonization of space... with a great writeup about our annual Analog Astronaut Conference we put on at Biosphere2!
Scientists are baffled by a mysterious orb found two miles underwater.
Futurism spoke to researchers from the NOAA's ongoing Alaska Seascape 5 mission, the latest installment of the agency's efforts to fully map the Gulf of Alaska's seafloor.
🛰️🪨 #Lucy en route pour les astéroïdes troyens a photographié l'astéroïde Dinkinesh, le premier des 10 astéroïdes que la sonde visitera au cours de son voyage de 12 ans. Lucy a effectué ces deux images les 2 et 5 septembre à 23 millions de km de la cible.

Murchison Minerals has been served an eviction notice not once, but twice by the Innu government for Uashat mak Mani-utenam.
The area the mining company states it is “eager” to explore is in Innu territory. Despite the “sheer number of high priority targets” identified and the “huge potential” of the Nickel-Copper-Cobalt project in Quebec, the Innu are determined to keep Murchison out.
#Exploration#Lune : Intéressant diagramme de Armchair Aerospace qui montre la durée de vie des différents atterrisseurs lunaires et rovers. Sans surprise, ceux qui ont de la longévité sont ceux équipés de système à radioisotopes pour survivre à la nuit lunaire.
Note : On a toutefois des doutes sur l’activité des missions lunaires chinoises car peu de communications. Les dernières images de Yutu-2 datent de juin 2023
🌑 Totalement inattendu : Avant de l'éteindre pour la nuit lunaire, l'ISRO a ordonné à l'atterrisseur #Vikram de rallumer son moteur et de s'élever de 40 cm au-dessus du sol. Il a atterri à 30-40 cm plus loin.
ISRO ne cache pas son envie d'une mission de retour d'échantillons lunaires. #espace#exploration#Inde#chandrayaan3
The Luna-25 spacecraft, en route to the Moon, suffered a major glitch today. That could mean 0 successes for Russia's entire post-Soviet deep-space program.
